Meta refresh is a legacy method of instructing a web browser to automatically refresh the current web page or frame after a given time interval, using an HTML meta element with the http-equiv parameter set to "refresh" and a content parameter giving the time interval in seconds. It is also possible to instruct the browser to fetch a different URL when the page is refreshed, by including the alternative URL in thecontent parameter. By setting the refresh time interval to zero (or a very low value), this allows meta refresh to be used as a method of URL redirection.
Place inside <head> to refresh page after 5 seconds:
<meta http-equiv="refresh" content="5">
Redirect to http://example.com/ after 5 seconds:
<meta http-equiv="refresh" content="5; url=http://example.com/">
Redirect to http://example.com/ immediately:
<meta http-equiv="refresh" content="0; url=http://example.com/">
